【 摘 要 】

OBJECTIVE: With base in the studies cineangiocardiography of pacients with pulmonary atresia (PA) with ventricular septal defect (VSD), to identify in the groups proposed by BARBERO MARCIAL, subgroups with similar morphological characteristics, to measure their central pulmonary arteries (CPA) and major aortopulmonary collateral arteries (MAPCA), thereby establishing their implications in surgical treatment. METHOD: Sixty three patients were classified in groups A (15), B (40) and C (8) between january 1990 and june 2001. Patients with complete cineangiocardiograms prior to the first surgical intervention were included in this study, being calculated the pulmonary arterial index (PAI), the major aortopulmonary collateral arterial index (MAPCAI) and the total neopulmonary arterial index (TNPAI = PAI + MAPCAI). Surgical treatment was considered palliative (PT), definitively palliative (DPT) and definitive (DT). RESULTS: Nine subgroups were identified, A (A1 and A2), B (B1, B2, B3, B4 and B5) and C (C1 and C2). In group A, the PAI of patients for DT was higher than for PT patients (p=0,0092). In group B, the TNPAI of DT patients was greater than for PT patients (p=0,0959). In group C, the MAPCAI in DPT patients was lower than in PT and DT patients. In the group A was not mortality, in the group B was of 17,5% and in the group C was of 12,5%. CONCLUSIONS:Among the groups A, B e C was possible to identifiy nine subgroups, the morphologic and morphometric characteristics allowed to suggest the surgical treatment in the patients of the group A had larger chance of TD, the group B of TP and the group C of TPD. The mortality presented larger correlation with the morphologic characteristics that with the morphometric.
